The Kamojang geothermal power plant in West Java, Indonesia has officially started producing geothermal-based green hydrogen and will now supply the Senayan Hydrogen Refueling Station. The green hydrogen plant (GHP) was built by state-owned electricity company PT PLN, making this the 22nd GHP that the company has built.

Green hydrogen, in this case, is produced from the condensation water coming from the Kamojang geothermal power production process. This achievement also makes the Kamojang geothermal power plant the first geothermal-based green hydrogen produced in Southeast Asia.

The operations at Kamojang increases the green hydrogen output of PT PLN by up to 4.3 tons per year. PLN states that there are further plans to increase the GHP capacity at Kamojang. In total, PT PLN produces 203 tons of green hydrogen per year across all facilities in Indonesia. 128 tons are used as hydrogen vehicle fuel, while the remaining 75 tones are used for plant operational needs.

PLN President Director Permawan Prasodjo further described this green hydrogen output as being enough to fuel 438 cars per year, assuming that each car covers 100 kilometers of distance per day. The green hydrogen output displaces up to 1.59 million liters of fuel imports per year for domestic use.

PT PLN continues with its efforts to expand the installed geothermal power capacity in Indonesia, having announced offers for partnerships for the development of several potential sites across the nation. More recently, PLN signed a partnership with Tanzania Electric Supply Co Ltd (TANESCO) to support geothermal development in Tanzania.
